Claims
- 1. A threshold assembly for spanning bottoms of vertical jambs of an entryway, said threshold assembly comprising:an elongated unitarily molded body defining an upwardly open channel along an inside edge portion and a support substrate projecting outwardly from said channel to an outside edge; a sill plate attachment slot formed in said elongated body; a sill plate mounted on said body covering and supported by said support substrate, said sill plate having an outside edge portion profiled to fit over said outside edge of said support substrate, and an inside edge; said molded body being formed with an upstanding nosing along said inside edge portion, said nosing forming an inside wall of said upwardly open channel; said sill plate being formed with a vertical wall along its inside edge, a first portion of said vertical wall extending downwardly to engage with said sill plate attachment slot to secure said sill plate to said body and a second portion of said vertical wall extending upwardly to define a dam; and a threshold cap disposed in said upwardly open channel for underlying a closed door.
- 2. A threshold assembly as claimed in claim 1 and wherein said unitarily molded body is made of plastic.
- 3. A threshold assembly as claimed in claim 1 and wherein said unitarily molded body is made of a plastic composite comprising a plastic and a filler.
- 4. A threshold assembly as claimed in claim 3 and wherein said plastic composite is blown to exhibit a cellular core structure.
- 5. A threshold assembly as claimed in claim 4 and wherein said filler is wood flour.
- 6. A threshold assembly as claimed in claim 5 and wherein said wood flour comprises about 20 percent by volume of said plastic composite.
- 7. A threshold assembly as claimed in claim 6 and where said plastic is polypropylene.
- 8. A threshold assembly as claimed in claim 1 and wherein said molded body defines a nosing along the inside edge of said body, said nosing forming an inside wall of said upwardly open channel.
- 9. A threshold assembly as claimed in claim 8 and further comprising a nosing cover covering said nosing.
- 10. A threshold assembly as claimed in claim 1 and wherein said sill plate is formed of extruded aluminum.
- 11. A threshold assembly as claimed in claim 1 and further comprising jamb boots integrally formed with said molded body on ends thereof.
- 12. A threshold assembly as claimed in claim 1 and wherein said support substrate is formed with spaced lateral ribs for supporting said sill plate.
- 13. A threshold assembly as claimed in claim 1 and wherein said molded body is formed with a ledge along an outside edge of said upwardly open channel and wherein said sill plate attachment slot is defined beneath at least one inwardly extending tab disposed along said ledge, said downwardly extending portion of said vertical wall covering said ledge and said at least one tab and including an outturned hook sized and positioned to extend onto said slot to hold said sill plate securely in place on said molded body.
- 14. A threshold assembly as claimed in claim 1 and wherein said threshold cap is a non-vertically adjustable threshold cap that may be selectively positioned along the length of said upwardly open channel to a desired location.
- 15. A threshold assembly as claimed in claim 1 and wherein said threshold cap is a vertically adjustable threshold cap.
- 16. A threshold assembly as claimed in claim 15 and wherein said upwardly open channel has a floor and wherein said adjustable threshold cap includes adjustment lugs that slidably rest on said floor so that said threshold cap may be selectively positioned along a length of said upwardly open channel to a desired position.
- 17. A threshold assembly as claimed in claim 1 and further comprising a sidelight panel cap disposed in said upwardly open channel, said sidelight panel cap and said threshold cap each being selectively positionable along a length of said upwardly open channel to desired positions.
- 18. A threshold assembly as claimed in claim 1 and wherein said support substrate is formed with spaced transversely extending ribs along its length for underlying and supporting said sill plate.
- 19. A threshold assembly as claimed in claim 18 and wherein said end portions of said molded body are sufficiently wide to accept fasteners to attach jambs to said threshold assembly and to allow cutting, honing, and notching operations.
- 20. A threshold assembly as claimed in claim 19 and further comprising stress relief features formed in said end portions of said molded body.
- 21. A threshold assembly as claimed in claim 19 and wherein said support substrate further includes at least one relatively wide region located intermediate said end portions.
- 22. A threshold assembly comprising:a unitarily molded body defining an elongated upwardly open channel from which a support substrate extends outwardly to an outside edge; an attachment slot formed along said molded body; a sill plate mounted on said molded body covering and supported by said support substrate, said sill plate having an outside edge portion disposed along said outside edge of said support substrate and an inside edge portion formed with a vertical wall; said vertical wall defining an outside wall of said upwardly open channel and having a downwardly projecting portion disposed in said attachment slot holding said sill plate in place on said body and an upwardly projecting portion forming a dam; and a threshold cap disposed in said upwardly open channel.
- 23. A threshold assembly as claimed in claim 22 and wherein said molded body is formed of plastic.
- 24. A threshold assembly as claimed in claim 22 and wherein said molded body is formed of a plastic composite comprising a plastic and a filler.
- 25. A threshold assembly as claimed in claim 24 and wherein said filler is wood flour.
- 26. A threshold assembly as claimed in claim 25 and wherein said wood flour comprises from about 10 to about 50 percent by volume of said composite.
- 27. A threshold assembly as claimed in claim 24 and wherein said filler is rice hulls.
- 28. A threshold assembly as claimed in claim 22 and wherein said molded body defines an upstanding nosing along an inside edge portion of said body and further comprising a nosing cover covering said nosing.
